After using aggregate method in Grid, search doesn't work.

Error message: "No generic method 'Sum' of type 'System.Linq.Enumerable' is compatible with and with provided type arguments"

 

Thanks.

Hello Abdurrahman,

Thank you for the image and details provided.

In general, the pointed issue could be caused by the property of the Model for the Sum aggregate. Here are examples:

The fastest route to getting you up and running is if you could provide a runnable, isolated, sample project. Examining this project will let us replicate the issue locally and further troubleshoot it.

Looking forward to hearing back from you.
